The 1200 V blocking voltage gives headroom for switching into inductive loads without avalanche failure — that's the margin between the peak line voltage and the device's breakdown limit. This relay is designed for mounting on available cooling surfaces — the low power consumption claim means the voltage drop across the output is low enough that a standard metal panel or heatsink suffices without forced air, provided the ambient stays within the datasheet's thermal derating. ## Integration notes Screw terminal connections, 22.5 mm width — fits standard DIN-rail enclosures. The 48-600 V operating range covers 400 V three-phase line-to-line and 480 V industrial supplies. The 24 V DC control input is compatible with PLC digital outputs; no external power supply needed for the coil side. Blocking voltage of 1200 V means it can handle the back-EMF from switching inductive loads like contactor coils or small transformers without external snubbers in most cases.","metaTitle":"Siemens 3RF3190-1AA05-0KN0 SIRIUS 3RF31 Solid-State Relay, 9","metaDescription":"Siemens SIRIUS 3RF3190-1AA05-0KN0 solid-state relay, 1-pole 22.5 mm, 90 A 48-600 V / 24 V DC, blocking voltage 1200 V.
